Virtual Return Feedback Suppressor Block - Extron electronics XMP 240 C AT User Manual

Virtual Return Feedback Suppressor Block

Use the feedback suppressor when there is an indication of feedback during live operation.
Dynamic filters automatically detect feedback on a live mic channel, and engage a set of
up to 5 fixed and 15 dynamic filters to counteract feedback at the detected frequencies.
The dynamic filters act in a "first in, first out" rotation. If all 15 dynamic filters are employed
and an additional feedback frequency is detected, the first feedback frequency detected is
overwritten.
To avoid a new feedback frequency overwriting a previously detected frequency, up to 5
dynamic filters can be transferred into fixed filters. Once a dynamic filter is transferred into a
fixed filter, it can only be overwritten by manually assigning a new frequency to the filter.
